[Pr.6] Rotation direction setting
Set the relation of the positioning direction (increment direction or decrement direction of [Md.20] Current feed value) and the
pulse output. For the relation of "Forward run pulse output, Reverse run pulse output" and "CW/A phase/PULSE signal, CCW/
B phase/SIGN signal", refer to the following.

Ex.
The following figure shows the pulse outputs of when [Pr.5] Pulse output mode is set to the CW/CCW mode and the
positioning of current feed value increment and of current feed value decrement is executed.

When this area is changed from 0 to 1, check if the upper limit switch and lower limit switch operate properly
with JOG operation. If any malfunction is identified, check and correct the wiring. If any malfunction is
identified, check and correct the wiring.
